OK... Are you able to reproduce the problem reliably?

If so, can you provide me with a binary tcpdump or wireshark dump? If
using tcpdump, then please use something like

   tcpdump -w /tmp/dump.out -s 90000 host myserver.foo.bar and port 2049

Please also try to provide a netstat dump of the current TCP connections
as soon as the hang occurs:

  netstat -t

Cheers
